Abstract
A scroll compressor may include a shell, a compression mechanism, and a sealing apparatus. The compression mechanism may be contained within the shell and include a compression member. The compression member may include an aperture extending radially there a surface. The sealing apparatus may be contained within the shell and include a first seal member and an actuator. The first seal member may be pivotally supported relative the compression member and may be movable from a first position wherein a sealing portion of the first seal member is in a sealing engagement with the surface and a second position wherein the sealing portion of the first seal member is displaced radially outwardly from the surface. The actuator may be engaged with the first seal member and configured to displace the first seal member from the first position to the second position.
